Dog ownership is associated with reduced eczema in children with dog allergies

30.09.2010
Children with eczema, a chronic skin condition that often begins in childhood, have a greater risk of developing asthma and food allergies. The number of children with eczema is rising, but the reasons for this are unclear.

A new study soon to be published in The Journal of Pediatrics examines the relationship between pet ownership and eczema. Researchers found that dog ownership among children with dog allergies may reduce the risk of developing eczema by age 4 years; cat ownership, however, may increase the risk among children with cat allergies.

Dr. Tolly Epstein and colleagues from the University of Cincinnati and Cincinnati Children's Hospital Medical Center gathered data from 636 children enrolled in the Cincinnati Childhood Allergy & Air Pollution Study (CCAAPS), a long-term epidemiologic study examining the effects of environmental particulates on childhood respiratory health and allergy development. Children enrolled in the study are considered at high risk for developing allergies because they were born to parents with allergies. The researchers focused on several potential risk factors for developing eczema, including dog and cat ownership. The children were tested for 17 separate allergies on a yearly basis from ages 1 through 4 years, and the parents completed yearly surveys.

The results provided interesting information regarding pet ownership. The researchers found that children who tested positive for dog allergies were less likely to develop eczema by age 4 years if they owned a dog before age 1 year. According to Dr. Epstein, "Children with dog allergies who did not own dogs were 4 times more likely to develop eczema."

Unlike dog ownership, cat ownership seemed to have a negative effect on children with cat allergies. "Children who owned a cat before age 1 year and were allergic to cats based on a skin allergy test were 13 times more likely to develop eczema by age 4 years," Dr. Epstein explains. She notes, however, that children who were not allergic to cats were not at an increased risk for eczema if they owned a cat. Dr. Epstein suggests that parents of children at risk for eczema may want to consider these findings when choosing a family pet.

The study, reported in "Opposing Effects of Cat and Dog Ownership and Allergic Sensitization on Eczema in an Atopic Birth Cohort" by Tolly G. Epstein, MD, MS, David I. Bernstein, MD, Linda Levin, PhD, Gurjit K. Khurana Hershey, MD, PhD, Patrick H. Ryan, PhD, Tiina Reponen, PhD, Manuel Villareal, MD, James E. Lockey, MD, MS, and Grace K. LeMasters, PhD, appears in The Journal of Pediatrics, DOI 10.1016/j.jpeds.2010.07.026, published by Elsevier.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
